Description
The OPB755N reflective assembly
features a phototransistor output
designed to decrease low-level light gain
while not affecting the high-level light
gain. Available with two mounting tabs as
OPB755T.
Available with PC Board mountable
leads as OPB750 series. Photologic
®
output sensors available in
OPB760/OPB770 series.

(3) Methanol or isopropanol are recommended as cleaning agents. Plastic housing is soluble in
chlorinated hydrocarbons and ketones.
(4) Photocurrent is measured using an Eastman Kodak Neutral White test card having a 90%
diffuse reflectance as a reflecting surface. Reference: Eastman Kodak, Catalog #1257795.
(5) I

is the photocurrent measured with current to the input diode and a 5% reflecting
surface.
